My question is: If I was going to start a blog network, say for instance, like SBnation or Bleacherreport or glam media, would it be smarter for me to have each blog have its own domain? Example; Say your blog is about New York sports, and there is keywords I want to rank for. The keywords are new york yankees xl, new york knicks xl, and new york rangers xl. Should I have a seperate domain and site for each 4 sports teams? Something like this..... Newyorkyankeesxl.com newyorknicksxl.com newyorkrangersxl.com or would it better to have just 1 site and list all the teams in a category? If I started 1 site named newyorksports.com, then have the catagories as new york yankees xl, new york knicks xl, and new york rangers xl. I was thinking if I want to turn a network like this into a long term type thing it would be better to have 1 big site for marketing purpose. That way advertisers can easily see the site there ads are on. But then i think it would be better to have seperate domains at first for SEO purpose, and then later on just make the big site and join all the blogs together on 1 site. Or maybe not. Thoughts?
